IMPROVEM ENT IN PLOWS.

Specification forming part of Letters Patent No. 205,657, dated July .2,1878; application filed May 14, 1878.

To all whom it may concern:

Be it known that I, LORENZO LING, of Pulaski, in the county of Oswegoand State of New York, have invented certain new and useful Improvementsin Flows; and I do hereby declare the following to be afull, clear, andexact description of the invention, such as will enable others skilledin the art to which it pertains to make and use it, reference being hadto the accompanying drawings, which form part of this specification.

My invention relates to an improvement in plows; and it consists in thepeculiar construction and arrangement of parts, whereby a better, moreeasily adjustable, and a more efficient plow is produced, as will bemore fully described hereinafter.

Figure l is a side elevation of my invention. Fig. 2 is a plan view ofthe same, and Figs. 3 and 4 are detail views.

(t represents the beam, which is cast in a single piece with thestandard 1), part c, to which the land-side d is secured, and a part toreceive the point g and mold-board h. Upon the rear edge of the standardis formed the extension t, and through the inner end of this extensionis made the slot f, through which passes the bolt 0, which unites theinner ends of the handles together. To each side of the extension isbolted an arm, I, to the outer ends of which the handles m are bolted.These arms serve as fulcrums, upon which the handles move.

By loosening the bolt 0 and bearing down or raising up upon the handlesthe outer ends can be raised or lowered to any desired degree to suitthe convenience of the person plowing.

By means of the construction here shown both handles can be adjusted byloosening but a single bolt, and no additional parts are necessary tothe plow except the two arms I.

The front end of the mold-board does not reach to the front sharp edgeof the standard, while the front cutting-edge of the point g projectssome distance in advance of it. In the space formed between these twoparts is placed the cutter a, which is secured to the standard by meansof the bolt q, as shown. This cutter is so formed that its front edgeforms a continuation of the front edge of the point, and has aprojection, s, upon its lower top of the point. As a flange on its outerside catches over the front edge of the standard, as the projection 8holds it at the bottom, and as the bolt q secures it in place, it willreadily be seen that the cutter cannot be displaced by any usage of theplow, but can be readily removed for the purpose of being sharpened.

The part c of the casting is recessed, so as to'receive the land-sideproper, and this landside projects some three or four inches outwardbeyond the side of the beam, so as to throw the beam in between theland-side and the mold-board. By placing the beam in this position itruns parallel to the furrows, the draft of the horses is in a straightline with the beam, the plow runs steadier, draws easier, and there isless danger of breaking the beam than there is when the beam is put onin the usual manner.

I ain aware that adjustable handles for plows are not new, and also thathandles have been secured to wings cast on the standard; and I do,therefore, not claim such as my invention. In such latter case, as knownto me, it either wing should become broken, which is often liable tohappen, it will be not only great trouble but serious inconvenience andexpense to repair the plow.

In my invention the wings or links I are made separate and detachablyconnected to the plow-extension 'i, so that either or both of them canbe easily and quickly removed and others substituted in case ofbreakage. The extension i being recessed, the said links are held firmlyin their places thereon by a single bolt, as shown.

Having thus described my invention, I claim- In a plow having thehandles adjustably secured to the standard, the standard b, formed withthe arm or extension 1', which is longitudinally recessed on both sides,and the links 1 Z, detachably secured in the recesses on said arm, incombination with the handles m m and the fastening-bolts, substantiallyas and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 10th day of May, 1878.
